Question

prove that the sum of all angle of triangle is 180 degree​

Answer 1

Step-by-step explanation:

Angle had Three sides

So all the sides are equal and have same angle

let one side of equitorial triangle be x.

So, x=60°

Therefore, 3x = 60 × 3 =180°

Hence, Proved.

Answer 2

Answer:

there are three angles in a triangle so by angle sum property we can prove it

Step-by-step explanation:

x+x+x=180,then3x=180,x=60,and in equilateral triangle one angles is 60
